In Part I, Effects of ''Gamma Radiation on Cytogenetics and Reproduction of Male Amblyomma americanum,'' male lone star ticks were exposed to 0.5, 1, 2, 3, 4, 8, and 16 krads prior to feeding. Testicular squashes were made, and chromosomal aberrations were described. Timing of spermatogenesis was not affected; however, frequency of abnormal spermatocytes and rounded and elongated spermatids increased as radiation dosage increased. Untreated females mated to irradiated males remained attached to their hosts longer than control females did. Few of the females paired with treated males oviposited. Length of preoviposition period and numbers of eggs produced by individual females were not influenced by dosage levels of males. Percent hatch of eggs was decreased by irradiation of male parent. No hatch occurred at 2 krads or above. Weights of individual larvae appeared to increase with increasing dosage of male parents. Most eggs weighed 60-80 ..mu..g; larvae weighed 40-60..mu..g. Irradiation of ticks as a potential biological control measure was discussed. Part II, ''Orientation to Light and Humidity in Haemaphysalis leporispalustris and Dermacentor variabilis,'' compared behavioral preferences of a host-specific and a broad-host-species.
